Granted: 2008-04-01
Abstract: A system and process for the recovery of oil from the pyrolysis of material containing hydrocarbons such as shredded vehicle tires. The system utilizes a pair of sequentially positioned packed towers to recover at least 95% of the oil contained in the pyrolysis gases. The first packed tower operates above the dew point of the water vapor in the pyrolysis gases to insure that no water is condensed and obtain a primary oil fraction having oil with a high flash point of about 60.degree.C or greater and a primary vapor fraction containing additional oils, fuel gases and water vapor. The primary vapor fraction is fed to the second packed tower which operates below the dew point of the water vapor to condense the water and oil having a low flash point of 34.degree.C or below, and provide a secondary vapor fraction containing valuable fuel gases.

Title: Insulated heat shield
Inventor: CHEN COLIN CHING-HO
IPC: F01N13/14
Filed: 2002-06-11
Granted: 2011-10-04
Abstract: A heat shield provides thermal insulation and reduced noise transmission for under-the-hood vehicular engine components, such as exhaust manifolds. The structure is formed in three layers: an outer metal layer to provide structural integrity, a center insulation layer to isolate heat and dampen noise, and an inner metal layer directly adjacent the shielded component for reflecting heat back to the shielded component. As disclosed, the insulation layer is sandwiched between the two metal layers. The heat shield is formed in two integral mating halves to define a unitary structure containing grommets. The grommets incorporate capscrews rotatably secured in respective halves of the structure for attachment to mounting bosses on the component. Finally, the edges of the two metal layers of the heat shield are folded over to prevent injury to installers, and to reinforce the heat shield structure for enhancing its useful life under severe conditions of vibration and heat.

Abstract: Heart and brain fatty acid binding proteins (H-FABP, B-FABP) are markers for TSEs, especially CJD. The invention provides a diagnostic assay for either of these markers, preferably by enzyme immunoassay using a specific antibody thereto. Since H-FABP is also a marker for acute myocardial infarction (AMI), to distinguish CJD from AMI requires an assay specific to AMI, e.g. using troponin-1 or CK-MB as a marker, also to be carried out.

Granted: 2012-01-03
Abstract: In some aspects, each cell in the communications system can be designed to operate in accordance with a set of back-off factors that identify the reductions in peak transmit power levels for the channels associated with the back-off factors. The back-off factors are defined to provide the required power to a large percentage of the users while reducing the amount of interference. In some other aspects, the cells operate using an adaptive reuse scheme that allows the cells to efficiently allocate and reallocate the system resources to reflect changes in the system. A reuse scheme is initially defined and resources are allocated to the cells. During operation, changes in the operating conditions of the system are detected and the reuse scheme is redefined as necessary based on the detected changes. For example, the loading conditions of the cells can be detected, and the resources can be reallocated and/or the reuse scheme can be redefined. In yet other aspects, techniques are provided to efficiency schedule data transmissions and to assign channels to users. Data transmissions can be scheduled based on user priorities, some fairness criteria, system requirements, and other factors. Users are assigned to available channels based on a number of channel assignment schemes. Channel metrics are also provided, which can be used to prioritize users and for channel assignments.
